In what seems to be your price range, I would recommend staying away from the "budget" electrics---too much can go wrong. I do suggest considering an upright machine rather than a table top if you have the room. The Gamma uprights (5003/6004) are nice. Also, I disagree with Irvin's caution against the Neos 1000 (actually, of the machines you list, the Neos 1000 would in fact be my choice)-- in my view, glide bars are not really inconvenient and other attributes of that machine (simplicity and durability) very much outweigh the so-called inconvenience (that said, the Neos is not ideal if you anticipate fan patterned racquets). There are some good treads to search on here to take advantage of before your purchase. Good luck.
Stay away from electric machines in this price range. I highly recommend any of the Gamma XST machines. Gamma has a great turn table. The clamps are nice and easy to clean, the mounting is annoying by today's six point mount standards but still simple. Gamma has amazing customer support, John is one of the best in the business.
Prince Neos is a nice machine too. The two point mounting is great because you have no blocked grommets, it is much easier to mount improperly though. I have strung plenty of sticks on this machine and I always come away annoyed with the clamps. I know they are simple and great but I guess I am spoiled and get to appreciate having fixed clamps instead of the glide bars.
Now my favorite part tools.
Clippers: I use the Xuron LX Micro Shear; they make cheaper but this one seems a little more sturdy
Bent Nose Pliers: Again Xuron Needle Nose pliers
Awl: I don't like sharp awls, I mainly use them to widen grommets and push a string out of the way. Kimony short awl is great, the bent awl is nice because it is a little thinner but you can accomplish most anything with the short one
Starting Clamp: Must buy! I like the new Babolat tool but the gamma is great as well. Keep them clean. It basically does everything, tie knots, bridge a short string, backs up the machine clamps. If I had to choose one tool I had to have this is it.
Setting of Awl is great if you string a lot and hate the heavy lifting of straightening with your fingers. I love my Babolat but RAB and Kimony make them as well.
